A lot of his work was developed at IMPA (Brazils Institute for Pure and Applied Mathematics), which has historically been somewhat connected to french mathematics universities. But, yeah, our best minds still go abroad to become fully developed.
The big problem in Brazil is that our basic education is crap. We do have good higher institutions, but a lot of the people who end up there never had a good base.

and this is what made me angry, our best researchers needs to leave the country to work because here they don't have a proper support, and when they finally succeed in something the people remember that he is brazilian like it was a determinant factor.
